2017 E98 2.8L USA Duramax Support

22 December 2016

EFILive is pleased to release 2017 E98 2.8L Duramax support for USA based vehicles. The 2017 USA based E98 is the first diesel platform to use GM's tougher controller security processes. This means the end user must now concern themselves with the security negotiations prior to reading or flashing the controller which adds a number of new steps to the tuning process. The security requirements for 2014-2016 USA based vehicles, and 2014-2017 non-USA based vehicles remain unchanged.

Security is managed by the Controller Authorization module contained in the EFILive V8 Scan and Tune software. The basic process requires users to:

Attempt to read or flash the controller to obtain the unauthorized auth-code. Because the controller is not yet authorized, the read or flash will fail with the error message: $0552 Reading and flashing are not yet authorized for this controller.

Send the unauthorized auth-code to an authorization code provider to obtain an authorized auth-code.

Enter the authorized auth-code into the EFILive software.

Continue to read or flash the controller using the normal EFILive process.
